3 Claims. (01. 123-148) "This invention relates to spark intensiflers and it is particularly adapted for use on internal combustion engines and is preferably adapted to be 5 giseted in the ignition circuit to the distributor Referring to the accompanying drawing, which is made a part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a vertical section through the device, Figure 2, a detail view showing contact washers and insulation between them, and

Figure 3 is a detail view showing a split sleeve forming a contact plug. p

In the drawing numeral indicates a casin formed of suitable insulatingmaterial such, for example, as bakelite.- The casing is preferably made separable and the two parts are placed together so as to be held together by friction or they may be secured together by some suitable cement: ing material. The cap portion of the casing is provided with a socket 11 into which extends the outer end of a conductive'pin 12. A.pin 13 is preferably secured in the bottom portion of the casing and held in position by means of anut 14. A sleeve 15 split at its outer end is preferably threaded upon the lower end of the'pin 13.- The split end of the sleeve is adapted to be inserted in a socket and held therein by friction produced by the tension of the split portion of the sleeve. Within the casing is seated a metallic washer 16 which engages the inner end of the metallic pin 13. A resistance coil 1'! is-positioned within the casing with one end in engagement with the washer 16 and the other end upon another metallic washer 18. A third metallic washer 19 engages the inner end of the pin 12. A thin insulating sheet or disk 20 of mica is positioned between the two last named washers. Particular importance is attached to the use of mica as an insulating material between the washers. This disk provides a sparkgap between the washers 18 and 19. The two 'washers are spaced apart by the disk 20 but are so arranged that the sparking occurs around the edges of the washers. The effect of this is an intensifying of the spark to the distributor. The washersare dished as shown in Figure 2 when not under tension When put under the tension of coil ll they flatten out with 'their edges engaging the edge of the mica disk 20 to hold it in place., The device may be inserted in the ignition circuit wherever most convenient. As shown, the particular form'of the device isadapted to be inserted in the distributor head. The ignition line to the distributor .head

is pulled out and my spark intensifierisplaced in series with the ignition line to the distributor. The split sleeve of my device is inserted into the distributor head and the ignition line is inserted in the hole in the cap of the casing of my device. When used on an automobile engine the device 90 may be readily inserted on practically all makes of cars without changing any of the wiring or other equipment on the engine. It is only necessary to pull out the ignition wire to the distributor I head, insert my device in place therein and insert the ignition wire in my device. The whole adaptation may be made in a few minutes. The device is simple, inexpensive, readily adaptable to known makes of cars and functions most efficiently to intensify the spark in the ignition sys- .70 tem.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawing and described in the specification, but only as indicated by the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letgo ters Patent, is: v

1. A spark intensifier comp'rising a casing having a contact element in each end, a resistance coil in said casing having one end in electrical contact with one of said elements, a metallic 35 washer in said casing in contact with the other of said elements, a second washer, said second washer being engageable by the other end of said coil, an insulating disk positioned between said washers, said washers being normally dished but go when under tension of said spring having their edges brought into gripping en agement with the edge of the disk. v

2; A spark intensifier comprising a casing composed of a body portion and a cap portion, one of said portions having a contact pin extending through the end, the other portion having a socket therein, a contact pin positioned with one end at the bottom of the socket and extending through the end of the said portion, a resistance 10o coil positioned in said casing, a metallic plate forming electrical contact withone end of the coil and one of said contact pins, a pair of dished metallic plates positioned between the other end of the coil and the other contact pin, said plates having an insulating disk between them and adapted to be sprung to engage and hold said insulating disk in place when said cap portion and said body portion are secured together.

3. A spark intensifier comprising a casing compositioned between the other end oi. the coil and the other contact pin, a mica disk positioned between said plates, said plates being dished when said cap and said body'portion are separated but being sprung to form flat plates, the edges of whichengagethemicadisktoholdthediskin place when the cap is secured upon the body portion.
